I need to backup my computer before OSX El Capitan

I have IMAC 21.5 10.7.5 2011: 1) is - it really worth upgrading to El Capitan? (2) do I need to backup before the upgrade?

Yes. You must back up before any important upgrade on your Mac.

Honestly, you should have a valid and test the implementation of the backup plan at any time. Losing data are a certainty, the only question is when it will happen.

    If you use a perpetual Photoshop and formatted your disc version of starting without disabling your activation of Photoshop, you also Adobe supports help you activate Photoshop once you retrieve your serial number.  The startup disk formatting would destroy that credential of Activation Photoshop machine which is registered in the database of the Adobe activation server. Which reduces the activation numbers you have to use.  If you have Photoshop installed on a second computer that means that you have no free activation available as well, even with your key you can't activated the machine.

  • Need to backup my system on a CD - R

    I have a laptop of Dell anchored C/600. It has interchangeable floppy drive-DVD readers. Computer indicates the size of the file to large to install diskette. This computer has been interrupted since ' 09. Started, updates installed. Rebooted, logged, error 2 ServicePak has not installed. Uninstalled.Restated reinstalled. Now need to backup systems. Registry. and files. My exwife was the computer nerd. all new, it's me.     Neeeeed Heeeelp Plllllleeeaaasssee.

    If you are planning a complete backup of your system, using CD - R blank is not practical. A CD - R disc has a maximum capacity of 650-700 MB; I'm sure that your system is using a minimum of 4-5 GB of disk space, or (much) more. Writable DVD or external hard drive should be used.

    To see how much space disk occupies your system click on the Start button, then right-click Workstation, from the context menu, select Explorer.

    In the my computer window, right-click on the main drive in your system, probably the drive Local (c), in the right pane, in the context menu click Properties.

    Just above your disk image, you will see used space.

  • I come to me on my computer and everything was gone. All my files, shortcuts and backround have simply disappeared. It's like I've never been on my computer before. I have nothing! How to get everything back?

    I come to me on my computer and everything was gone. All my files, shortcuts and backround have simply disappeared. It's like I've never been on my computer before. I have nothing! How to get everything back?

    You have been discharged into a temporary user account. It may be a glitch, or your user account may be damaged. First try a system restore when things worked. If it suits it, fine. If it is not then your account is damaged and the best thing to do is to create a new user account and copy your data from the old to the new. I would also like to do a Chkdsk and then some hardware diagnostics on the hard drive and RAM to make sure that the material is solid.

    CHKDSK - click here to open the computer. Right click on the hard drive you want to check, and then click Properties. Click on the Tools tab and then, under error-checking, click check now. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

    To automatically repair problems with files and folders that the scan detects, select automatically fix file system errors. Otherwise, the disk check will simply report a problem, but not to fix them.

    To perform a full disk check, select search and attempt to recover bad sectors. This scan is trying to find and repair physical errors on the hard drive itself, and it may take much longer to complete.

    To check for errors file and the physical errors, select both automatically fix errors in file system and search for and attempt recovery of bad sectors.

    Click Start.

    Depending on the size of your hard disk, this may take several minutes. For best results, do not use your computer for any other tasks while it checks errors.

    Note: If you select automatically errors in file system of fix for a disc that is used (for example, the partition that contains Windows), you will be prompted, see the disk check for the next time you restart your computer.

    Corrupt user account - if your single administrative user account is damaged (and therefore have what one user account is A Bad Thing), you must log on to the built-in Administrator (disabled by default in Vista) account. From there, you can create a new user account for yourself. In these cases, I prefer not to copy the whole profile to a new way to do not copy the bits corrupt. I prefer a new user account to copy the data (documents, photos, emails, etc.). Here are the instructions to do this. I assumed that you had only an administrative account, then you might want to take a look at the "general recommendations for setting Up user accounts in Vista" at the end of this post.

    All this requires a certain level of computer skills. You know better and that take the machine to a competent local computer tech (not a type of BigComputerStore/GeekSquad place) is the best solution for you.

    Activation of the built-in administrator.

    Method 1. If you have an installation of Vista DVD (not a recovery DVDs), you can start the system with it. Select the default language, then select "repair your computer". Then select "Command Prompt". At the command prompt, type:

    NET user administrator / Active: Yes [Enter]

    If you do not have a Vista installation DVD, you can either make a bootable DVD of Vista repair in the file at this link:

    http://NeoSmart.net/blog/2008/Windows-Vista-recovery-disc-download/

    Note: All the Neosmart recovery disk downloads are torrent files. There is a good explanation of the torrent on the site Web of Neosmart files. You will need a torrent as muTorrent client to get the files. Torrent client will download the .iso file with which to create the bootable DVD.

    After net user, remove the bootable CD and restart the computer. You will now see an icon for administrator on the Welcome screen. Connect to this account.

    Method 2. Or you can use NTpassword to enable the built-in administrator. In both methods, you need third-party burning software such as Nero, Roxio or the free ImgBurn (http://www.imgburn.com ) to burn the .iso image image file, not in the form of data.

    http://home.eunet.no/pnordahl/ntpasswd/

    B. create a new user account for yourself and by copying data from your damaged to her user account

    1. you are now connected to the built-in Administrator account. Go to control panel > user accounts and create a new Standard user for your daily work. Let's call it "Sheldon" for this example. Also create an administrator user, called 'CompAdmin' (or 'Tech' or similar).

    4 Ouvrezunesession 'Sheldon' once for profile files are created. Now log off 'Sheldon' and 'CompAdmin '. In "CompAdmin", disable the built-in security administrator. Do this from a command prompt:

    Start > Search > type: cmd
    When cmd appears in the above results, right-click and choose "Run as Administrator". Provide the password/OK to the UAC prompt. Now, you will get the command prompt. Type:

    NET user administrator / active: No. [Enter] and exit the command prompt.

    5. always in 'CompAdmin', you want to open two windows explore side by side. Open computer and navigate to C:\Users\old-corrupted-account. Now, do that again, but navigate to C:\Users\Sheldon. Copy the data from 'old-corrupted-account' on records in 'Sheldon '. Remember your Favorites, bookmarks (if you use Firefox) and by e-mail if you use an email like Windows Mail client.

    6. When you are finished, log in to "Sheldon. All your stuff should be there. When you are sure to have what you need, you can remove the old man-corrupted-account control panel > user accounts.

    General C. recommendations for creating users in Vista:

    You absolutely don't want to have only one user account. As XP and all the other modern operating systems, Vista is an OS multi-user with system built-in accounts such as administrator, by default, all users and guest. These accounts should be left alone because they are part of the structure of the operating system.

    In particular, you do not want one account user with administrative privileges on Vista because the administrator account integrated (normally only used in emergencies) is disabled by default. If you use as an administrator for your daily work, and this account is corrupt, things will be difficult. It is not impossible to activate the built-in administrator to rescue things, but it will take third-party tools and work outside the operating system.

    The user account that is for your daily work must be a Standard user, with the extra administrative user (call it something like 'CompAdmin' or 'Tech' or similar) only it for elevation purposes. After you have created "CompAdmin", connect to it and change your normal user account Standard. Then log on to your regular account.

    If you want to go directly to the desktop and ignore the Welcome screen with the icons of the user accounts, you can do this:

    Start Orb > Search box > type: netplwiz [Enter]
    Click continue (or provide an administrator password) when you are prompted by UAC

    Uncheck "users must enter a user name and password to use this computer". Select a user account to connect automatically by clicking on the account you want to highlight and press OK. Enter the password for this user account (when it exists) when you are prompted. Leave blank if there is no password (null). MS - MVP - Elephant Boy computers - don't panic!
